Global Warming

Answer

Carbon dioxide, nitrogen dioxide, chloro fluoro carbons, hydrocarbons, and methane are called Earth heating gases. They trap radiation and prevent heat from leaving the earth's surface.

Answer

Greenhouse gases trap radiation and stop heat from escaping the earth's surface. This helps maintain the temperature of the earth.

Answer

When too many greenhouse gases collect in the atmosphere, too much heat is trapped. This leads to excess global warming.

Answer

The objective is to investigate the impact of greenhouse effect through simulation and to search methods to reduce global warming.

Answer

Two identical glasses of the same material are used so that the comparison is fair. Any difference in heating can then be linked to the covered and uncovered conditions.

Answer

Equal quantity of water should be put in both glasses, and the temperature of the water in both glasses should be noted using a thermometer before the experiment.

Answer

One glass is covered completely with an inverted glass bowl or jar to simulate the greenhouse effect. The other glass remains uncovered as the control.

Answer

Both glasses must be placed in open space so that sunlight falls directly on them. This helps show the difference in heating clearly.
